This bottom bracket is the same as our PF30, but with a shallower insert depth.

Our standard PF30 bottom bracket uses a deep insert for the strongest possible connection to the frame. This causes problems on some metal frames with wires running into the chain stay or with the internal cable guides on some frames. For these frames we have designed the PF30-L, same bottom bracket minus the insert guide and a few mm of contact area.

This bottom bracket fits specifically on many metal frames, the 2017 Cannondale SuperSix or Cervelo P5 series.
